thrust::device_free

inline void thrust::device_free(thrust::device_ptr<void> ptr)

device_free deallocates memory allocated by the function device_malloc.

The following code snippet demonstrates how to use device_free to deallocate memory allocated by device_malloc.

#include <thrust/device_malloc.h>
#include <thrust/device_free.h>
...
// allocate some integers with device_malloc
const int N = 100;
thrust::device_ptr<int> int_array = thrust::device_malloc<int>(N);

// manipulate integers
...

// deallocate with device_free
thrust::device_free(int_array);
